AbstractA data communications apparatus and a data communications method, which shows a list of normal devices to a user by removing abnormal devices from the list managed by the directory server when devices start to function abnormally. The devices transmit alive check data to the directory daemon at predetermined intervals. The directory daemon transmits the result obtained by receiving the alive check data to the directory server. The directory daemon also transmits a device management command to the directory server at predetermined intervals. The directory server deletes the devices which have not transmitted the alive check data for a predetermined time from a management list and transmits the management list to the alive devices. According to the above apparatus and method, only a list of currently normal devices is shown to a user by deleting abnormal devices from the management list of the directory server when devices become abnormal. Therefore, it is possible to check whether devices normally operate, to thus let the user conveniently use the devices.
